Maintenance of industrial machinery and HVAC systems.
This standard covers nonsupervisory work that is performed to repair and modify a variety of equipment and systems that achieve regulated climatic conditions. This work requires a knowledge of principles of air conditioning, the ability to recognize and determine the best method for correcting malfunctions and the skill to make repairs to a variety of air conditioning and cooling unit systems.
This standard is for use in grading nonsupervisory jobs involved in installing, maintaining, repairing, troubleshooting, and modifying single and multiple fuel heating and power boilers and associated auxiliary and pollution control equipment, hot air furnaces, and similar equipment systems. The systems and equipment provide steam, heat, or hot water for use in the operation of industrial and institutional facilities and equipment. This work requires knowledge of the principles of combustion, he
This standard is to be used for grading nonsupervisory jobs involved in the repair and maintenance of high speed elevator systems and moderate or low speed elevators, dumbwaiters, leveling ramps, and escalators to meet regulatory codes and work requirements. The work requires a knowledge of the construction, function, and maintenance procedures of dispatching or scheduling systems, systems components, driving and hoisting machinery, control mechanisms, guide structures, and car or platform equip
This standard covers nonsupervisory work involving the dismantling, repairing, relocating, modifying, maintaining, aligning, and installing of a wide variety of marine machinery, equipment, and systems such as propulsion machinery, propellers, rudders, cargo handling machinery, lifeboat davits, anchor handling gear, and missile tube equipment that are located aboard submarines, ships, and other floating craft. The work requires a practical knowledge of the mechanical, hydraulic, and pneumatic sy
at the grade 10 level, grade 11 production machinery mechanics independently determine the nature of the trouble and extent of repairs required on equipment that is usually complicated by more variables. They are expected to recognize the evidence of electrical or electronic malfunctions from indications in the mechanical, hydraulic, or pneumatic portions of the equipment, requiring
This standard covers nonsupervisory work involving the dismantling, repairing, relocating, modifying, maintaining, aligning, and installing of general nonproduction industrial plant machinery, equipment, and systems such as bridge cranes, towveyor/conveyor and pneumatic tube systems, sandblasting machines, and other industrial plant support machinery and equipment; service, industrial waste and flood control equipment such as compressors, pumps, and valves; and engraving machines, aircraft test
This standard is used to grade nonsupervisory general mechanical work involved in making a variety of repairs to powered ground and similar support equipment used for aircraft ground servicing; missile, aircraft, air control, and radar installations' powered support; field combat support; engineering and construction project support; and general utilities, including standby and emergency power generating systems. The systems repaired are made up of combinations of components such as: gasoline, d
